What is Dynamic Balancing?

Dynamic balancing definition: “Dynamic balancing is a way of balancing machines by rotating parts quickly and measuring the imbalance using electronic equipment. The imbalance measured can then be corrected by adding or subtracting weight from the rotating parts until the vibration is reduced.”

Basically, all machines have some form of residual vibration. Enormous vibration in rotating machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal thing to do would be to remove all causes of vibration and allow the machine to run completely smooth. The process of balancing is the removal or addition of weight to the device, so that this effective mass centre approaches the true axis.

In addition to dynamic balance, there is also static balance. When a part is statically balanced, the centre of gravity is on the axis of the rotation. This means the part will stay stationary at a horizontal axis, without the application of braking force. It also has no tendency to rotate due to the force of the gravity.

Benefits of dynamic balancing

When a machine is operating in balance, it is functioning as designed. Numerous consequences could result from having a machine in a smooth, well-balanced operating order. These outcomes include the following:

Make sure that you include a vibration analysis in your preventative maintenance program. Not only can it help to identify a problem, it can often lead to a solution as to what can be done before a major failure occurs.
